Submission in Islam specifically refers to submitting oneself to the will of God.
In the light and essence of Islam (Submission) and the Quran, there is no war which is holy; this, under any circumstances whatsoever. In fact the whole text of the Quran and the religion of Islam (Submission) revolves around the concept of peace, not war. To many people's ignorance, Islam (Submission) is also a word that share the same root of the Arabic word Salaam meaning peace. To Islam (Submission), war is unholy, Jihad must mean anything but holy war. 
Confusion has arisen in political discourse because the Arabic word for submission is jihad, which is more often used to refer to a divinely ordained "holy war".
